IMPROVEMENT 1N Bren-Monos AND BOTTOM-Bonos 'Thescheduie referred `to inthese Letters Patent and making part of the same Be it ltnow'n that I,ALBERT T. BU'rnAM, oiDt-trot, in .the county of Way-ne and State ofMichigan, have `invented anew and useful Imprcvei'ncnt in Brickthe bricktherefrom is avoided, by simply raising the lmold and allowing theliriekto remain upon the ,hot-

tour-board,which is provided with openings through it coincident withthe' partitions of the mold, the spaces -between the openings heiligleft thesiz'e, iniwidth, of

the molds themselves v- Tbis arrangement, of the molds and`betteln-board allows the brick to be` molded upon the board, upon whichthey may remain to bedried preparatory to being burned, the openingsabove mentioned aoi-'ding a free circulation of air n'pon the sides ofthe brick.

The arrangement also prevents the necessity of han ling and turning thebricks upon the yard, there- 4by caving them free from broken edges,&o., and 4' lrearlyor qniteas smooth `as pressed brick.

In the ordinary methotot' manufacturing bricks.

lthey are turned out of the Imolds upon the yard, and

must be turned in order to dry; thereby injuring the.l bricks-bybreaking oii the comers, and otherwise defacing them. l

AIn the accompanying.dra\vings" Fig, 1 represent-s a brick-mold, made ofany snit fable material, divided into equal compartments of the'required size by the partitions This mold is made without draw, thesidesA and ends being exactly ver tica-l. Fig. 2-represents abottom-board of a properwsze to lit the mold, and `provided'withopenings, b, through it, which openings are coincident with thepartit-ions a in the mold, leaving olid spaces, c, bet-Ween saidopenings, of the size of the compartments between'4 said. partitions.

Suitable guides or dowels may be employed to secure the fitting togetherof the mold and board.v

What I claim as my invention, and desire to secure bvLetters Patent,isf- .lhe bottomJooard B, provided with crosspieces o and openings b, inconnection with the brick-mold A,

provided withcross-partitions a corresponding with theopcnings b, andwith spaces d corresponding with the oross-pieees c\vhcn constructed andarranged to y op zrate as and for the purposes set forth.
